Furious because a small nation resisted the almighty German war machine Hitler ordered the attack on Yugoslavia. In Hitler's 'Order 25' the role for Luftwaffe was clear: the destruction of JKRV (Jugoslovensko Kraljevsko Ratno Vazduhoplovstvo - Yugoslovian Royal Air Force) and the bombardment of Belgrade.
For Operation 'MARITA', against Yugoslavia and Greece, the Luftwaffe dropped 1090 aircrafts (Luftflotte 4) and Germans were supported also by additinal 660 Italian and some Hungarian planes. JKRV was able to resist by totally 470 first line aircrafts, but only 269 planes were airworthy modern types. In first day of attack Luftwaffe concentrated mostly on Yugoslavian airbases, destroying a part of JKRV force before take off. But soon Yugoslavian pilots appeared in air...
The German attack came at the wrong time for the 102 eskadilju, 32 vazduhoplovne grupe as witnessed by its CO Mihajlo Nikolic:
".....In Mostar we were supposed to be relived by the Fighter Scholl from Nis. While waiting for them our planes were turning ready for their 100hrs check, because they all had from 110-130hrs flying time. The Me 109E had the Daimler Benz 601 engine, and the only repair shop for these engines was in Zemun. So on Saturday 5. April in the evening we landed on the Zemun airfield. The airplane of August Kovac engine failed while still on the runway, and the others were practically unflyable. But we were immediately included in the 51. vazduhoplovna grupa, which flew IK-3, but only had six of them-three each squadron. That night we were called by the CO of the unit Rupcic and gave as the following order:
- At dawn tomorrow morning you will patrol over the border part Vrsac-Bela Crkva where German tank units from Romunia are anticipated."
A member of these tank units, a tank gunner, describes the Major Diner StG 2 attack on a mountain pass fortification:
"A fine coating of dew covered the vehicles. Only a thin strip of slowly lightening sky above the mountains heralded the start of a new day. It was 5 am on the morning of 6 April. We looked at our watches. Fifteen minutes to go. As we adjusted our binocular, a pale dawn light started to seep down the hillside in front of us. The mountains behind rose out of a milky white morning mist. One more minute. There! To the west a machine gun rattled briefly. Then a muffled explosion. A few seconds of complete silence, then the whole front erupted into noise. Our own light flak units added to the din of the artillery.
Despite the racket, my ears picked up the thin drone of aircraft engines, growing louder every second. I knew from experience what it was, and pointed the glasses upwards. Sure enough, the dim shapes of approaching Stukas. Now they were circling above us, the dark red pin-points of their position lights plainly visible beneath the shadows of their wings.
They slowly began to climb, breaking into the clear light of the new day. More and more aircraft joined them as they headed towards the ridge of the mountains immediately to our front. One last circle, as it to make double sure of the target below, and then the first Ketten went into their dives. Even from here we could hear the familiar nerve-shattering howl of their sirens. And then the first bombs fell. The tiny black specs rained down on the enemy positions. The noise of the explosions echoed back unseen clefts in the mountains as Staffel after Staffel attacked. Soon pillars of yellow-brown smoke were staining the pristine whiteness of the high snowfields."
While Stukas of StG2 were attacking enemy positions and Me 110 were attacking all airfields in the general direction of the attack, a large formation of bombers from II./KG 4, KG 2 and KG 3 was joined by the fighters from II/JG 77, III/JG 77 and III/JG 54. A Yugoslav fighter-pilot during the Zerstorer run said: "When we were watching, almost all, of our fighter airplanes burning our CO said:
- It really is war. We will get paid double".
The approach of the bomber formation to Belgrade went really quiet, and only when the noise of multiple aircraft engines was reported from the hills surrounding Belgrade JKRV's response late due to the failure of the early warning system.
Kapetan 2. klase Mihajlo Nikolic:
"In the morning 6. April 1941 I took-off as first, with my wingman Milodrag Boskovic to follow the order. We returned after 50 min, when we landed we started to eat some sandwiches when from the office burst our CO giving us the sign to take-off. When we were strapping in he radioed us that German airplanes crossed the border at Subotica and were flying from South to Belgrade.
The officer ordering Nikolic to take-off was the CO at Zemun-Adum Romeo. 16 planes took-off.
The first was the IK 3 squardon of kapetan 1. Klase, who was escorted by narednik Dusan Vujicic. The second pair consisted of kapetan 1. razreda Todor Gojic his wingman was narednik Milislav Semiz. Dusan Borcic was leading the third pair and his wingan was Bamfic.
Mihajlo Nikolic continues
The IK-3s flew first because they got the information earlier, we followed them with seven Me 109E (there were ten, but one was unserviceable, and two were on patrol).
It was a clear day with a bit of haze and scattered clouds so we flew towards Sava river. When we were in the air, I looked back from habit and I saw that my wingman Milodrag Boskovic in confusion forgot to pull in his landing gear. I called him via radio but to no success, and only when I opened my landing gear, he cleaned out his gears and joined fighting formation. At first we saw nothing, then we spotted our planes diving into something. When we got closer, the sky immediately went black from German airplanes, and we flew into this turmoil not ever dreaming that Germans had an umbrella of fighters above us. First we saw the Stukas flying in groups of seven. There were so much targets that we didn't have to chose anything. I attacked one group from the left and bellow, but immediately the right side of the group descended for the gunners to have a clear shot. This was a trained tactic, but the group didn't break. We made a couple of runs, but didn't pay attention if there was any results. A little later I noticed that a Stuka was starting to burn, The group immediately-as being ordered-broke fearing an explosion.
Then I noticed that the He 111 were coming. I made a turn and told Boskovic that we are going for a group from behind because they are defended from the top and bellow. I started my attack carefully choosing my position, all concentrated in aiming...from nowhere a blast in the cabin and a German fighter almost rammed me with his wing, coming from the left.
My wingman didn't even saw him. That fighter got a good shot in me, but I to squeezing the trigger gave full left rudder and fired at him. The cabin was already filled with smoke. The fuel tanks are behind us and they could catch fire, we were told to put the fire out with a quick dive, I managed to do that, but when I wanted to apply throttle the engine did not respond. I don't see or hear Boskovic (I never saw him again). I started to chose where I will land, and between the villages Sakule and Baranda I notice a clearance with some stock on the left and right a field. I chose the field and I belly-land. I open the cabin and I notice there is blood on my flying suit, I got shot in my left leg."
In fact Boskovic wasn't found until 1955, when he and he's Me 109 were recovered from Dunav river near the village of Kovilj which is about 2min flying time in general heading towards Belgrade to the place that Nikloic crash-landed his Messerschmitt. Some parts of his Messerschmitt are kept in the Yugoslav air force museum, including the DB 601 engine.
The other pair of JKRV Me 109�s were Milo� �unič and D�ord�em Stojanoćem.
The pair closed in on the He 111�s, one bomber was shot down by �unič. The pair quickly turned to the fighters and defended themself untill they ran out of ammo. Me 109 flown by �unič was hit a couple of times, and he bailed out. He came to earth dead. His wingman survived.
The flight of IK-3�s lead by the talented aerobatic champion and flight instructor Savo Poljanec from Maribor soon reached the first wave of enemy bombers.
Poljanec lead the group on to the bombers but they were seperated because of the German Me 109 diving on them. Poljanec was now alone and fighting with the guns of 27 bombers. The experienced aerobatic pilot made an immelman turn and came back down the side of the formation concentrating on the right bomber of the last three. Just before the bomber was engulfed in fire the tail gunner watched the victorious Poljanec climb over the formation. Then on the alititude of 6000m Poljanec noticed that a formation of German Me 109 fighters were preparing an attack on him. Poljanec evaded the first fighter, and then started a high speed pursuit, with a couple of short bursts from Poljanec the Me 109 began lossing altitude and was aparently out of control. His joy was to be shortlived because in the next moment, he was attacked by the next fighter who was following him closely all this time. Poljanec felt a sharp pain in his right shoulder and his engine started to quit. Seeing there was no point of proceding, he shut off his engine and started spinnig. The trick worked since the enemy fighters sure of their kills started climb again. His spin became uncontrolled now and only his great experience as an aerobatic pilot enabled him to exit this spin, and this only at minimal altitude. Poljanec was now flying his bullet ridden IK 3 towards Zemun trailing a glycol trail behind him. Just before landing he was strafed by a Me 110 and one of his shell exploded behind the seat that Poljanec was ocupaying. But all in all he managed to land safely and was immediately put in hospital.
Worth mentioning here is that Poljanec in a IK-3 flew a lot of mock dogfights against Yugoslavian Me 109E usually flown by Boris Cijan.
Over another part of Belgrade, over Senjak the second pair consisting of podporočnik Borčič and Bamfič, was looking for a good fight, but they didn�t find any enemies, so they separetad to increase their chances.
Borčič flew toward the Rumanian border and then returned to Belgrade. Over Zvezdara he caught up with 20 Do 17�s enemy bombers that was heading towards the centre of the capital. He attacked the last three and sent one Do 17 in the Danube river. The same scenario as happaned again as with the Poljanec. The German Me 109�s were diving on him, but Borcic gained just a spot of advatage, so he could shot down a Me 109E. Now he was alone, and German fighters were trying to encircle him, but they weren�t suceding untill Borcic run out of ammo. He was shot down on the banks od Danube 15km nort of Belgrade. His last fight was observed by a lot of spectators in Belgrade city. After the war the remains of his IK 3 was lifted from the river, and it revealed that no big �white 10� was worn on the fusleage, but just a little �black 10� on the rudder.
His wingman Bamfić was also fighting with the Me 109s over Batajnica. His IK 3 was alo badly damaged, and he was coming in for landing, but was bounced by two Me 109s. To avoid certain death Bamfic was forced into a series of steep turns, with his wingtips almost touching the ground. He crash-landed near the airfield. His IK 3 was completly destroyed during the landing, but Bamfić was not hurt.
Vujičić had to return to the airfield due to cooling problems.
The pair Gogić and Semiz shot down a Stuka.
A pilot of the bomber stream piloting one of StG 77 Stukas was lucky to avoid Yugoslav fighters:
"After the Green hedgerows of the Normandy countryside, the warm browns and greys of the local landscape were still unfamiliar to our eyes. The morning sun was glinting off the peaks of the Transylvanian Alps at our backs as we were approaching the unmistakable silver ribbonod the Dunav, the frontier between Rumania and Yugoslavia. The hazy outlines of a large city appeared in the distance-Belgrade!
Below us the first few burst of enemy flak. But nothing to worry about. Those of us who'd been through Poland and France had seen much worse. The city is much clearer now. The white tower-like buildings bright in the morning sun. The Staffeln opens up as pilots prepare to dive. Our target is a the fortress which gave the city it's name. Perched high above the promontory where the Sava joins Dunav, it couldn't be missed.
I felt the jolt as our bomb was released. We leveled out and turned back for base at high speed, ready to prepare for the next mission. As we retired I saw the fortress ringed in smoke and flames. Fires had also been started in the royal palace and the nearby main railway station. Soon smoke hung over the whole city like a great grey shroud.
On 6 April 1941, during the first mission of Luftwaffe's I.(J)/LG 2 - low-level attack against the base of the 36th Fighter Group base at Rezanovacka Kosa at Kumanovo shortly after 6:00 am - the Bf 109s of this unit got involved in a dogfight with the Hawker Fury biplanes of 36th FG above this airfield. Without any reported losses, I.(J)/LG 2 (equipped with Bf 109 E-7) made the following claims of Hawker Furys: Lt. Geisshardt - 4 Furys (victories Nos 14-17), Olt. Clausen - 3 Furys (Nos 6-8) and Gefr. Quatember - 1 Fury (No 3).
During the first mission of JG 77 - escort to the raid against Belgrade - between 07.30 and 08.40, 56 Bf 109 of JG 77 were involved in furious dogfights with Yugoslav fighters. Oberleutnant Erich Friedrich of Stab/JG 77 claimed a Yugoslav Bf 109 as his third victory. In II./JG 77, the following pilots claimed one Bf 109 each: Olt. Jung (his victory No. 3), Ofw. Petermann (7), Lt. Zuzic (1), Fw. Ftr
